The present results demonstrate that a sufficient posterior shift of the spinal cord and neurologic improvement will not be obtained after posterior decompression surgery in the K-line (-) group. Our new index, the K-line, is a simple and practical tool for making decisions regarding the surgical approach for cervical OPLL patients.

We developed the first nomogram that can accurately predict postoperative hypertension cure in patients with primary aldosteronism. This nomogram can help clinicians calculate the probability of postoperative hypertension cure in patients with primary aldosteronism and objectively inform them of their hypertension outcome before laparoscopic adrenalectomy.

Fork-head box protein A1 (FOXA1) is a “pioneer factor” that is known to bind to the androgen receptor (AR) and regulate the transcription of AR-specific genes. However, the precise role of FOXA1 in prostate cancer (PC) remains unknown. In this study, we report that FOXA1 plays a critical role in PC cell proliferation. The expression of FOXA1 was higher in PC than in normal prostate tissues (P = 0.0002), and, using immunohistochemical analysis, we found that FOXA1 was localized in the nucleus. FOXA1 expression levels were significantly correlated with both PSA and Gleason scores (P = 0.016 and P = 0.031, respectively). Moreover, FOXA1 up-regulation was a significant factor in PSA failure (P = 0.011). Depletion of FOXA1 in a prostate cancer cell line (LNCaP) using small interfering RNA (siRNA) significantly inhibited AR activity, led to cell-growth suppression, and induced G0/G1 arrest. The anti-proliferative effect of FOXA1 siRNA was mediated through insulin-like growth factor binding protein 3 (IGFBP-3). An increase in IGFBP-3, mediated by depletion of FOXA1, inhibited phosphorylation of MAPK and Akt, and increased expression of the cell cycle regulators p21 and p27. We also found that the anti-proliferative effect of FOXA1 depletion was significantly reversed by simultaneous siRNA depletion of IGFBP-3. These findings provide direct physiological and molecular evidence for a role of FOXA1 in controlling cell proliferation through the regulation of IGFBP-3 expression in PC.

Object Granulocyte colony-stimulating factor (G-CSF) has neuroprotective effects on the CNS. The authors have previously demonstrated that G-CSF also exerts neuroprotective effects in experimental spinal cord injury (SCI) by enhancing migration of bone marrow–derived cells into the damaged spinal cord, increasing glial differentiation of bone marrow–derived cells, enhancing antiapoptotic effects on both neurons and oligodendrocytes, and by reducing demyelination and expression of inflammatory cytokines. Because the degree of angiogenesis in the subacute phase after SCI correlates with regenerative responses, it is possible that G-CSF's neuroprotective effects after SCI are due to enhancement of angiogenesis. The aim of this study was to assess the effects of G-CSF on the vascular system after SCI. Methods A contusive SCI rat model was used and the animals were randomly allocated to either a G-CSF–treated group or a control group. Integrity of the blood–spinal cord barrier was evaluated by measuring the degree of edema in the cord and the volume of extravasation. For histological evaluation, cryosections were immunostained with anti–von Willebrand factor and the number of vessels was counted to assess revascularization. Real-time reverse transcriptase polymerase chain reaction was performed to assess expression of angiogenic cytokines, and recovery of motor function was assessed with function tests. Results In the G-CSF–treated rats, the total number of vessels with a diameter > 20 μm was significantly larger and expression of angiogenic cytokines was significantly higher than those in the control group. The G-CSF–treated group showed significantly greater recovery of hindlimb function than the control group. Conclusions These results suggest that G-CSF exerts neuroprotective effects via promotion of angiogenesis after SCI.
